IMPROVEMENT IN BOOT-CRIMPING BLOCKS.

Specification forming part of Letters Patent No. 142,369, datedSeptember 2, 1873; application filed April 5, 1873.

To all whom it may concern:

Be it known that we, HENRY BORDNER and DENIS SULLIVAN, of Virginia City,Storey county, State of Nevada, have invented an Improved Boot-CrimpingBlock; and we do hereby declare the following description andaccompanying drawings are sufficient to enable any person skilled in theart or science to which it most nearly appertains to make and use oursaid .invention or improvement without further invention or experiment.

Our invention relates to a jointed crimpingblock for crimping the upperleathers of boots, in' order to form them into the proper shape to fitthe foot. Our improvement consists in constructing the block so that theupper can be securedupon it by means of tacks and clamps, in the usualway, while it is almost straight, after which the upper is stretched tothe required shape by shifting the position of the two parts of thecrimp by means of a screw.

In order to more fully illustrate and explain my invention reference ishad to the accompanying drawings forming a partof this specification, inwhich Figure 1 is a side elevation with a portion broken away to showthe screw. Fig. 2 is a side elevation. Fig. 3 is a back view.

A represents the leg, and B the vamp or foot-blocks of our improvedcrimper. To the lower end of the leg-block we secure a plate, C, thefront end of which projects downward, forming a lug, cl. The opposingend of the vamp-block is-also faced with a plate, 0, the forward end ofwhich projects upward, and is separated into two lugs, c, forming afemale leaf, between which the lug d is secured, so as to form ahingejoint, by which the two blocks are united. vamp-block B is boundwith a narrow band, f, while the lower end of the leg-block A is boundwith a wide plate, g, which is cut away at the instep of the crimper, soas to allow the foot-block to be shifted about the joint until it standsat a right angle to the legblock. The binding-plate 9 extends downwardtoward the back side of the crimpers, so as to cover The upper end ofthe the triangular space, which is formed when w the two parts areopened about the hinge. A long screw, j, which is turned by a crank, K,passes longitudinally through the rear part of the leg-block, so thatits lower end will pass through the face -plate 0 at the lower end ofthe block, and serves, when turned down, to force the vamp or blockupward.

To crimp, the upper of a boot, the "crimper is straightened, and theupper tacked upon it, using two nails upon each side0ne at the top andone at the bottom. The usual clamps are then applied at the openingbehind the joint, so as to hold the upper firmly to the block at thispoint. The screw j is then turned down, so that its lower end will pressupon the end plate 0 and force the vamp to its rectangular position,thus drawing the upper to the required shape. If the upper should happento wrinkle a few rubs will remove the wrinkles and leave the leathersmooth. It is evident that as the screw j passes down, and the strainincreases, the angle at which the screw touches the plate 0 will change,and, by the incline, give to the screw an increased power.

With a crimper constructed in the abovedescribed manner we are able todo almost twice the amount of the work with much less trouble and laborthan can be done with the ordinary crimper.

Having thus described our invention, what we claim, and desire to secureby Letters Patent is l The leg-block A, and vamp or foot-block B unitedby the joint d c, in combination with the screw j passing through theblock A, and whose free end presses against the plate 0, operating onthe plate at different distances from the joint as the foot-block israised, substantially as and for the purpose described.

In witness whereof we hereunto set our hands and seals. 7
